Your rotor blades can take a beating after multiple flying trips and can get damaged with multiple uses over time. We’ll list out some of the damages you can expect on your blades and the best remedies for each.
Corrosive damage can appear on the surface of your blades and start out as minimal damage. However, over time, this type of damage can easily get out of control and even destroy your whole blade. The reason for corrosion lies in the metal material returning to their original state of oxides and salt and largely depends on several factors.
Some examples include the operating environment, choice of materials, paint and primer systems, and the preventive measure taken by the operator. What you use to build and care for the blades can determine the severity of corrosion damage and the right fix to restore it.
Some common solutions include using freshwater with soap to wash down your blades, followed by a coating of corrosion prevention compound. It’s good to wash all the metal parts separately and completely apply the compound to get the absolute best results.
Erosion usually occurs when your blade hits water, dirt, volcanic ash, or sand. Special manufacturer-installed erosion protection systems like erosion strips (made out of metal or polyurethane) provide the safest defence for such damage.
Lacquer touch-up paint application will also help your blade because it protects the exposed metal without further chipping. This touch-up can be done whenever needed in moderation and should be applied before the blade becomes too damaged or exposed.
Big and Small Cracks
If left alone for a while, cracks in the blade, big or small, can result in structural damage or failure of the rotor blade. It’s good practice to routinely inspect your blade of any crack or defects. Even a small dent in the training edge of a blade can quickly turn into a major crack.
Soap and water can help you out once again, as it’s a common test used on blades to locate any leaks. Otherwise, if you spot a crack in your blade, no matter the size, be sure to get it checked out by a professional you trust.
